Thanks for all your replies!
I think that perhaps the best thing upgrade wise would be to do the same as the youtube guy - do the rear cable+hydraulic keeping one lever with the cutout and tge front fully hydraulic.
Unless there are any fully hydraulic brakes with cutoff.

Hi!
I bought a RadRhino (EU version of RadRover) in the winter and rode 700km (435miles). All good except for the brakes. I needed to adjust them 2 times already and now it seems like the front disc is bent as well.
Does anyone else have issues with brakes? Did anyone upgrade them for hydraulic?
Thanks,
